Grouping apparatus, grouping program of communication devices

摘要

A grouping apparatus of communication devices for use in a communication system, in which a plurality of communication devices are connected respectively via a communication medium and capable of communicating with each other, includes a sequence determination section that detects a time sequence of inputs to an input section for generating a participation request signal from one's and the other communication devices. Constitution of a secure group between one's communication device and the other communication devices is implemented when a time sequence of inputs to the input section of one' s and the other communication devices meets a predetermined specific rule. In this manner, grouping of a plurality of specific communication devices can be carried out easily and safely. <IMAGE>
